Banker$$s Algorithm, written in C

For this project, you will write a program that implements the banker$$s algo$-$rithm discussed in Section $8\mathrm{.}6\mathrm{.}3.$ Customers request and release resources from the bank. The banker will grant a request only if it leaves the system in a safe state. A request that leaves the system in an unsafe state will be denied. Write this program in C$.$

The Banker

The banker will consider requests from n customers for m resources types, as outlined in Section $8\mathrm{.}6\mathrm{.}3.$ The banker will keep track of the resources using the following data structures:

#define NUMBER OF CUSTOMERS $5$

#define NUMBER OF RESOURCES $4$

$/*$ the available amount of each resource $*/$

int available$[$NUMBER OF RESOURCES$]$;

$/*$the maximum demand of each customer $*/$

int maximum$[$NUMBER OF CUSTOMERS$][$NUMBER OF RESOURCES$]$;

$/*$ the amount currently allocated to each customer $*/$

int allocation$[$NUMBER OF CUSTOMERS$][$NUMBER OF RESOURCES$]$;

$/*$ the remaining need of each customer $*/$

int need$[$NUMBER OF CUSTOMERS$][$NUMBER OF RESOURCES$]$;

The banker will grant a request if it satisfies the safety algorithm outlined in Section $8\mathrm{.}6\mathrm{.}3\mathrm{.}1.$ If a request does not leave the system in a safe state, the banker will deny it$.$ Function prototypes for requesting and releasing resources are as follows:

int request resources$($int customer num, int request$[])$;

void release resources$($int customer num, int release$[])$;

The request resources$()$ function should return $0$ if successful and $1$ if unsuccessful.
